here is a picture of a spoof board they are now made by divingeneering ..these are Prototype boards but they are working very well .....

a NIMH version only has 25 sense cables and a Lead acid Version has 39 sense leads ...

to build a NIMH just add a jumper to block out the part not used or order a nimh version from divengineering .....

BCM Spoof

the wiring diagram for the wires is in the 2001 ranger ev wiring manual you can download from fordrangerev.com

One of the problems I personally have had with conversions is the darn gauges go totally Wankers (maybe not a word but I am using it) the gauges would never stay to where I could depend on them .. I would rather they were stuck on full then to keep going to the bottom and not allowing me to use the whole pack and if you keep driving without resetting the historical data after about 3 months you would end up with a truck that would not go 5 miles without all the lights blinking at you on the dash ...

Thus the answer was to make the BCM happy ... just like a happy Wife or Girlfriend add a Spoof to make it think that the modules are always perfect then just use the voltage to control the gauges (still not perfect but will always show a gas gauge of full when charged) ... seems to work much better ....
